DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0056] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0057] In the following description, the terms "first, second, ..." are used solely to distinguish different objects and do not imply any similarities or connections between the objects. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to directions during normal use. The directions "left" and "right" refer to the left-right directions shown in the corresponding schematic diagrams, which may or may not be the left-right directions during normal use.

[0058] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising that element. The term "connected," unless otherwise specified, includes both direct and indirect connections.

[0059] In some specific embodiments, the liquid delivery device can be used to deliver any washing liquid, which may include a main detergent or a main detergent and an auxiliary detergent, wherein the auxiliary detergent may be a softener. The liquid delivery device can directly deliver the detergent into the washing drum of the washing machine. The liquid delivery device can also pre-mix the washing liquid with water and then deliver the mixture into the washing drum of the washing machine.

[0060] In some embodiments, combined Figure 1 and Figure 2 The liquid delivery device 10 includes a liquid separation box, a liquid storage part 200, a liquid pump 400 and a suction tube 700. A liquid separation chamber 110 is formed inside the liquid separation box, and the liquid separation box is provided with a liquid inlet 150 and a first liquid outlet 111 connected to the liquid separation chamber 110. The detergent can enter the liquid separation chamber 110 from the liquid inlet 150 and be output from the first liquid outlet 111. Optionally, the liquid separation box also has a water inlet. The detergent can be mixed with water in the liquid separation box and then output from the first liquid outlet 111, so that the detergent can be in more sufficient contact with the clothes in the washing drum of the washing machine. A liquid storage chamber 210 is formed inside the liquid storage part 200. The liquid storage chamber 210 is used to store detergent, and the liquid storage part 200 can be in a first direction (the first direction is as shown in FIG. 1 ). Figure 1 and Figure 2 The liquid storage member 200 slides relative to the liquid separation box, so that the liquid storage member 200 can be loaded into or removed from the liquid separation box by moving the liquid storage member 200 relative to the liquid separation box.

[0061] The suction tube 700 is located in the liquid storage chamber 210 and has a third end and a fourth end opposite to each other. Figure 8 The first connecting port 721 is connected to the second through hole 220, and the suction tube 700 extends from the third end to the bottom surface of the liquid storage chamber 210 to form a fourth end and the fourth end has a suction port 741. The detergent in the liquid storage chamber 210 can be sucked through the suction tube 700, and the extracted detergent then enters the tubular portion.

[0062] The liquid storage member 200 is provided with a second through hole 220, the central axis of which is parallel to the first direction. The liquid pump 400 is located outside the liquid separation box, and the liquid inlet end of the liquid pump 400 is connected to the liquid storage chamber 210 through the first through hole 120, the second through hole 220, and the suction tube 700, so that the liquid pump 400 can extract detergent from the liquid storage chamber 210. The liquid outlet end of the liquid pump 400 is connected to the liquid inlet 150 of the liquid separation box, so that the detergent extracted by the liquid pump 400 can enter the liquid separation chamber 110 through the liquid inlet 150, and then be discharged through the first liquid outlet 111. The liquid inlet end of the liquid pump 400 can be directly connected to the first through hole 120 or indirectly connected to the first through hole 120 through a pipeline, and the liquid outlet end of the liquid pump 400 can be directly connected to the liquid inlet 150 or indirectly connected to the liquid inlet 150 through a pipeline.

[0063] It is understandable that the liquid separation box also has a water inlet pipe (not shown in the figure). The liquid pump 400 pumps out a specific amount of detergent stored in the liquid storage chamber 210 through the liquid pumping pipe 500 and returns it to the liquid separation chamber 110 through the return pipe 600. The water inlet pipe lets water into the liquid separation chamber 110, mixes the detergent and water in the liquid separation chamber 110, and then sends the mixture to the washing drum through the liquid outlet.

[0064] It is understood that the liquid extraction pipe 500 and the liquid return pipe 600 can be physically the same pipe. For example, a portion of the pipe is located inside the liquid extraction pump 400 and is powered by the liquid extraction pump 400. The upstream of the pipe is the liquid extraction pipe 500, which is connected to the detergent storage container; the downstream is the liquid return pipe 600, which is connected to the liquid separation box. Exemplarily, the liquid extraction pipe 500 and the liquid return pipe 600 can be physically integrated with the liquid extraction pump 400, for example, they can be integrated with the housing of the liquid extraction pump 400, but at least one of the liquid extraction pipe 500 or the liquid return pipe 600 is independent of the housing of the liquid extraction pump 400 so that a sensor can be installed on at least one of the liquid extraction pipe 500 or the liquid return pipe 600. The utility model provides a liquid delivery device, which includes a liquid separation box with a liquid separation cavity 110 formed therein, a liquid storage component 200 located in the liquid separation box and forming a liquid storage cavity 210 therein, a suction tube 700 located in the liquid storage cavity 210 and having opposite third and fourth ends, and a liquid pump 400 located outside the liquid separation box, wherein the liquid separation box has a first through hole 120, the liquid storage component 200 has a second through hole 220, the third end of the suction tube 700 is connected to the second through hole 220, the liquid inlet end of the suction pump 400 is connected to the liquid storage cavity 210 through the first through hole 120, the second through hole 220 and the suction tube 700, the liquid separation box has a liquid inlet 150 and a first liquid outlet 111 and the suction tube 700 is connected to the liquid storage cavity 210, and the liquid separation box has a liquid inlet 150 and a first liquid outlet 111. The liquid outlet end of the liquid pump 400 is connected to the liquid inlet 150. The liquid pump 400 can extract the detergent in the liquid storage chamber 210 and input it into the liquid separation chamber 110 through the liquid inlet 150, so that the detergent can be output from the first liquid outlet 111. It can be understood that the liquid pump 400 can extract a certain amount of detergent from the liquid storage chamber 210 and input it into the liquid separation chamber 110 according to the needs of the user, so that the detergent is mixed with water in a certain proportion in the liquid separation chamber 110 and then output from the first liquid outlet 111 to enter the washing drum. That is, detergent can be automatically added according to user needs during the washing process, which improves the washing effect while reducing the safety hazards caused by manually adding detergent during the washing process.

[0065] In some embodiments, combined Figure 1 and Figure 2The liquid storage member 200 is a liquid storage bottle, which can be taken out of the liquid separation chamber 110. By taking out the liquid storage bottle as a whole or putting it into the liquid separation chamber 110, when the detergent in the liquid storage bottle is exhausted or almost exhausted, the liquid storage bottle can be replaced as a whole, or detergent can be refilled into the empty liquid storage bottle and then put into the liquid separation chamber 110. The liquid storage bottle is also provided with a ventilation hole 230. It should be noted that in order to reduce the possibility of leakage of the detergent in the liquid storage bottle, the liquid storage bottle is a sealed structure except for the second through hole 220. 00 is in communication with the second through hole 220, the liquid storage chamber 210 forms a closed cavity. As the liquid pump 400 continuously extracts the detergent from the liquid storage chamber 210, the air pressure in the liquid storage chamber 210 continues to decrease, which makes it increasingly difficult for the liquid pump 400 to extract the detergent from the liquid storage chamber 210. By providing the ventilation through hole 230, the liquid storage chamber 210 can be connected to the atmosphere through the ventilation through hole 230, so that the air pressure in the liquid storage chamber 210 is kept balanced, and the liquid pump 400 can continuously extract the detergent from the liquid storage chamber 210. Optionally, as Figure 6 As shown, a breathable valve is provided in the breathable hole 230. The breathable valve allows gas to enter the liquid storage chamber 210 through the breathable hole 230, while preventing the detergent in the liquid storage chamber 210 from leaking out of the liquid storage chamber 210 through the breathable hole 230. For example, the breathable valve can be a one-way valve 260. The specific installation method of the breathable valve in the breathable hole 230 can be similar to the installation method of the one-way valve 260 in the second through hole 220.

[0066] At the same time, combined Figure 3 and Figure 4The liquid delivery device 10 further includes: a liquid extraction joint 300, a liquid extraction tube 500, and a liquid return tube 600. The liquid extraction joint 300 is detachably connected to the liquid separation box. The liquid extraction joint 300 includes a tubular portion 310. The first end of the tubular portion 310 is located outside the liquid separation box, and the second end of the tubular portion 310, which is opposite to the first end, extends into the liquid separation cavity 110 through the first through hole 120. The second end of the tubular portion 310 extends along the first direction and can be communicated with the second through hole 220. It can be understood that when the liquid storage bottle is installed in the interior of the liquid separation box, the second end of the liquid extraction joint 300 can extend into the second through hole 220 to connect the liquid extraction joint 300 with the liquid storage cavity 210, so that the liquid extraction joint 300 can extract the detergent in the liquid storage cavity 210 to the outside of the liquid separation box. The liquid extraction connector 300 can be detachably connected to the liquid separation box in various ways. For example, the liquid extraction connector 300 can be detachably connected to the liquid separation box through a connecting structure. For example, the tubular portion 310 can be detachably connected to the liquid separation box by interference fit with the first through hole 120. The liquid extraction tube 500 connects the liquid inlet end of the liquid extraction pump 400 and the first end of the tubular portion 310. The liquid extraction pump 400 is connected to the liquid storage chamber 210 through the liquid extraction tube 500 and the tubular portion 310, thereby being able to extract the detergent in the liquid storage chamber 210. The liquid return tube 600 connects the liquid extraction pump 400 and the liquid inlet 150. The liquid extraction pump 400, which is disposed outside the liquid separation box, can input detergent from the liquid inlet 150 into the liquid separation chamber 110 through the liquid return tube 600. By arranging the liquid pump 400 outside the liquid separation box and detachably connecting it to the liquid separation box through the liquid extraction joint 300 and the liquid extraction tube 500, compared with the structure in which the shell of the liquid extraction pump 400 is integrated with the rear part of the shell of the liquid separation box, the liquid extraction pump 400 can be disassembled more conveniently when the liquid extraction pump 400 needs to be repaired or replaced, thereby improving the convenience of maintenance and care of the liquid delivery device 10. At the same time, the liquid extraction pump 400 is arranged outside the liquid separation box and connected to the liquid extraction joint 300 through the liquid extraction tube 500, which is different from the shape or appearance of the liquid separation box. When the shape changes, the liquid pump 400 can still be used in the liquid separation box, which improves the versatility of the liquid pump 400, and the liquid suction tube 500 is also exposed to the outside of the liquid separation box so that a sensor can be set on the outside of the liquid suction tube 500. Through the sensor, the liquid delivery device 10 can achieve more functions. For example, by setting the transmittance sensor 902, the bubble size or bubble density in the liquid suction tube 500 can be obtained, thereby realizing the detection of the detergent residue in the liquid storage chamber 210. For example, by setting the temperature sensor, the temperature of the detergent can be obtained.

[0067] In some embodiments, as Figure 5As shown, the liquid extraction connector 300 also includes a connecting structure 330 on the outer periphery of the tubular portion 310. The connecting structure 330 is detachably fixed to the outer surface of the liquid separation box via a connecting member. The provision of the connecting structure 330 can provide more installation space for the connection member, thereby making it easier for the liquid extraction connector 300 to be detachably connected to the liquid separation box. Optionally, a through hole can be formed in the connecting structure 330, and the outer surface of the liquid separation box has a threaded hole corresponding to the through hole. The connecting member is a screw. By passing the screw through the through hole and screwing it into the threaded hole, the liquid extraction connector 300 can be detachably connected to the liquid separation box.

[0068] In some embodiments, combined Figure 3 and Figure 4 The outer surface of the liquid-separating box is concave to form a first groove 170, and the inner surface of the liquid-separating box is convex to form a first protrusion 140. It can be understood that the first groove 170 can be formed on the outer surface of the liquid-separating box by a mechanical processing process such as stamping, so that the first groove 170 can be formed without reducing the wall thickness of the liquid-separating box, so that the liquid-separating box has sufficient structural strength; the first groove 170 is provided with a first through hole 120, and the connecting structure 330 is detachably fixed in the first groove 170 of the liquid-separating box through a connecting piece. By accommodating the connecting structure 330 in the first groove 170, the connecting structure 330 and part of the tubular portion 310 can be accommodated in the interior of the first groove 170, thereby reducing The volume of the small connecting joint protrudes from the outside of the liquid separation box, thereby reducing the possibility of interference between other parts or structures of the liquid delivery device 10 and the connecting joint. Moreover, the connecting structure 330 needs to form a mating surface with the part connected to the outer surface of the liquid separation box. The mating surface has higher processing precision requirements. If the entire outer surface of the liquid separation box is used as the mating surface, the processing cost and processing difficulty will increase. By providing a first groove 170 and making the connecting structure 330 detachably connected to the inner surface of the first groove 170, the inner surface of the first groove 170 is the mating surface and the outer surface of the rest of the liquid separation box is the non-mating surface, thereby reducing the processing cost and processing difficulty of the liquid separation box.

[0069] In some embodiments, as Figure 6 As shown, the liquid storage bottle includes a bottle body 240 and a bottle cap 250, and the bottle cap 250 is detachably connected to the bottle body 240. The inner surfaces of the bottle body 240 and the bottle cap 250 surround and form a liquid storage cavity 210. The end of the bottle body 240 is provided with a bottle mouth 241. When the bottle cap 250 and the bottle body 240 are assembled, the bottle mouth 241 is covered by the bottle cap 250. It can be understood that when the bottle body 240 and the bottle cap 250 are assembled, the bottle cap 250 covers the bottle mouth 241 so that the bottle cap 250 and the inner surface of the bottle body 240 form a closed liquid storage cavity 210. By separating the bottle body 240 from the bottle cap 250, the bottle mouth 241 can be exposed to the outside, so that detergent can be injected into the bottle body 240 through the bottle mouth 241.

[0070] Optionally, the bottle body 240 includes a main body portion and a bottleneck portion, the bottleneck portion extends out from the outer surface of the main body portion, and the radial dimension of the bottleneck portion is smaller than that of the main body portion, a first connecting thread is provided on the outer surface of the bottleneck portion, and the inner surface of the bottle cap 250 has a second connecting thread matching the first connecting thread, the bottle cap 250 and the bottle body 240 are detachably connected by the first connecting thread and the second connecting thread, and at the same time, a limiting abutment protrusion is provided on the side wall of the bottleneck portion, and a limiting abutment groove 251 is provided at the end of the bottle cap 250, and when the bottle cap 250 is assembled into place with the bottle body 240 by rotation, the limiting abutment protrusion abuts the limiting abutment groove 251, thereby enabling the circumferential assembly positioning of the bottle cap 250 to be achieved.

[0071] like Figure 7 As shown, the inner surface of the bottle cap 250 is convexly provided with a second protrusion 253, the second through hole 220 and the air-permeable through hole 230 both penetrate the second protrusion 253 and form an opening on the first surface of the liquid storage chamber 210 at the second protrusion 253, and the second through hole 220 is provided with an annular wall 252 on the outer periphery of the opening formed on the first surface, and the third end of the suction tube 700 can extend into the space surrounded by the annular wall 252, thereby realizing the circumferential limitation of the suction tube 700 by the annular wall 252, and at the same time, the annular wall 252 has a first positioning structure 2521, and the outer surface of the suction tube 700 has a second positioning structure 701. When the third end of the suction tube 700 extends into the space surrounded by the annular wall 252 and is connected to the second through hole 220, the first positioning structure 2521 is engaged with the second positioning structure 701, thereby further realizing the suction tube 700 through the action force between the first positioning structure 2521 and the second positioning structure 701. 00 circumferential positioning, wherein the first positioning structure 2521 and the second positioning structure 701 are any structures that can achieve locking. Exemplarily, the first positioning structure 2521 is convexly provided on the outer surface of the annular wall 252 to form a protrusion, and the second positioning structure 701 is a groove formed by the outer surface of the side wall of the suction tube 700 being concave, and the protrusion can be locked with the groove; Exemplarily, the first positioning structure 2521 is a positioning groove formed by the outer surface of the annular wall 252 being concave along the first direction, and the second positioning structure 701 is a positioning protrusion formed by the outer surface of the suction tube 700 protruding, and the positioning protrusion can extend into the positioning groove; Exemplarily, the first positioning structure 2521 is a first locking groove formed by the outer surface of the annular wall 252 being concave along the first direction, and the second positioning structure 701 is a second locking groove formed by the outer surface of the suction tube 700 being concave, and the first locking groove and the second locking groove can be locked with each other to form a mortise and tenon structure.

[0072] In some embodiments, as Figure 7As shown, the suction pipe 700 includes a first tubular portion 720 and a second tubular portion 730, and the second tubular portion 730 protrudes from the outer surface of the first tubular portion 720, thereby forming two non-parallel parts, so that the extension direction of the first tubular portion 720 is parallel to the first direction while the second tubular portion 730 can extend toward the bottom of the liquid storage chamber 210, thereby facilitating the installation of the suction pipe 700 and making the fourth end of the suction pipe 700 closer to the bottom of the liquid storage chamber 210, so that the suction pipe 700 can extract more detergent; wherein, the end of the first tubular portion 720 forms the third end, the first tubular portion 720 is connected to the second through hole 220 through the third end, the second tubular portion 730 extends toward the bottom surface of the liquid storage chamber 210, and the end of the second tubular portion 730 facing the bottom surface of the liquid storage chamber 210 forms the fourth end, and the fourth end has a suction port 741. Optionally, the second tubular portion 730 extends from the end of the first tubular portion 720 away from the third end, thereby forming a tubular structure similar to an L-shape; optionally, the second tubular portion 730 extends from the outer surface of the side wall of the first tubular portion 720 close to the end, thereby forming a cross pipeline.

[0073] Optional, such as Figure 7 As shown, the suction tube 700 also includes a base 710, which is located at the third end of the suction tube 700 and protrudes from the first tubular portion 720. A connecting hole is formed in the base 710, and the third end is connected to the second through hole 220 through the connecting hole. The base 710 extends into the space surrounded by the annular wall 252 and can abut against the inner surface of the annular wall 252, thereby further realizing the circumferential positioning of the suction tube 700.

[0074] In some embodiments, combined Figure 7 and Figure 8 The liquid storage bottle also includes a one-way valve 260, which is located in the second through hole 220 and blocks the second through hole 220, for allowing detergent to flow out and preventing detergent from flowing back. Specifically, an annular positioning boss is convexly provided on the inner surface of the second through hole 220, and one end of the one-way valve 260 is accommodated in the space surrounded by the annular wall 252 and abuts against the annular positioning boss, and the other end of the one-way valve 260 is accommodated in the interior of the first tubular portion 720 and abuts against the inner surface of the first tubular portion 720. It can be understood that the radial positioning of the one-way valve 260 is achieved by the inner surface of the first tubular portion 720 and the inner surface of the annular wall 252. At the same time, the one-way valve 260 is clamped between the annular positioning platform 2522 and the inner surface of the first tubular portion 720, thereby achieving axial positioning of the one-way valve 260.

[0075] It can be understood that the second through hole 220 is a longer hole. The third end of the first tubular portion 720 of the suction tube 700 is inserted into the second through hole 220 from one direction, and in the other direction, an annular wall 252 is protruding from the outer periphery of the second through hole 220. The second end of the tubular portion of the liquid suction connector 300 is inserted into the annular wall 252. The inner surface of the annular wall 252 is protrudingly provided with an annular positioning boss. The one-way valve 260 is clamped between the annular positioning boss 2522 and the inner surface of the first tubular portion 720.

[0076] In some embodiments, as Figure 9 When the cap 720 is in the closed position, the top end of the cap 720 is in the closed position, and the top end of the cap 720 is in the closed position, so that the cap 720 can be easily inserted into the cap 720. When the cap 720 is in the open position, the cap 720 can be easily inserted into the cap 720.

[0077] Among them, the number of abutment bosses 750 is greater than three, and each abutment boss 750 is arranged at intervals around the suction port 741, so that the abutment positions of the three abutment bosses 750 and the bottom surface of the liquid storage chamber 210 are in non-collinear positions, that is, a support surface is formed by three non-collinear support positions to more reliably support the suction tube 700, and support is provided by multiple abutment bosses 750 arranged at intervals, so that the detergent can enter the suction port 741 from the gap between adjacent abutment bosses 750, that is, while reducing the influence of the suction port 741 on the detergent suction, the suction tube 700 is supported.

[0078] Optional, such as Figure 9 As shown, along the extension direction of the abutment boss 750, that is, in the direction from the fourth end to the bottom surface of the liquid storage chamber 210, the cross-sectional area of the abutment boss 750 decreases gradually. The cross-sectional area is a plane perpendicular to the extension direction of the abutment boss 750. It can be understood that the abutment boss 750 gradually shrinks while extending toward the bottom surface of the liquid storage chamber 210, thereby further reducing the obstruction of the abutment boss 750 to the suction port 741.

[0079] In some embodiments, as Figure 10As shown, the bottom surface of the liquid storage chamber 210 is concave to form a second groove 243, and the fourth end of the suction tube 700 extends into the second groove 243 so that the suction tube 700 can extract more detergent. At the same time, the fourth end of the suction tube 700 is also provided with an abutment boss 750, which extends from the fourth end to form an abutment end 751, and the abutment end 751 abuts against the bottom surface of the second groove 243, so that the suction tube 700 can extract more detergent while being more stably supported.

[0080] In some embodiments, as Figure 11 As shown, the liquid storage member 200 is a liquid storage bottle, and the liquid delivery device 10 further includes a liquid storage bottle rack 900. A holding space 910 is formed inside the liquid storage bottle rack 900. In a first direction, the liquid storage bottle rack 900 can move relative to the liquid separation box, so that the liquid storage bottle can slide relative to the liquid separation box in the first direction, that is, the liquid storage bottle can slide relative to the liquid separation box through the liquid storage bottle rack 900. By setting up the liquid storage bottle rack 900, the sliding operation of the liquid storage bottle can be facilitated. In the case where there are multiple liquid storage bottles, each liquid storage bottle is set in a liquid storage bottle rack 900, and each liquid storage bottle can be simultaneously moved relative to the liquid separation box in the first direction through the liquid storage bottle rack 900. In which, the liquid storage bottle rack 900 can be pulled out of the liquid separation chamber 110 along the first direction. At the same time, the second end of the tubular portion 310 extends along the first direction, so that when the liquid storage bottle rack 900 slides along the first direction, the second end of the tubular portion 310 can extend into the second through hole 220 and communicate with the suction tube 700.

[0081] In the first direction, the liquid storage bottle rack 900 has a fifth end close to the bottle cap 250 and a sixth end opposite to the fifth end. The fifth end of the liquid storage bottle rack 900 is provided with a third through hole 920. When the liquid storage bottle is placed in the holding space 910, the bottle cap 250 extends into the liquid separation cavity 110 through the third through hole 920, so that the second end of the tubular portion 310 can more conveniently extend into the second through hole 220 provided in the bottle cap 250.

[0082] When the liquid storage bottle rack 900 is pulled out of the liquid separation chamber 110, the liquid storage bottle can be taken out of the holding space 910 or loaded into the holding space 910. It can be understood that when the liquid storage bottle rack 900 is pulled out of the liquid separation chamber 110, the opening of the liquid storage bottle rack 900 is exposed to the outside of the liquid delivery device 10, so that the liquid storage bottle can be loaded into the holding space 910 as a whole through the opening or taken out from the holding space 910 as a whole.

[0083] Optional, such as Figure 11As shown, the third through hole 920 extends to the bottom surface of the holding space 910. During the process of loading the liquid storage bottle, the bottle cap 250 can be extended into the third through hole 920 and the bottle cap 250 can be located near the bottom of the holding space 910, that is, the liquid storage bottle is in an inclined state with the bottle cap 250 low and the bottle body 240 high to facilitate the installation of the liquid storage bottle, and then the end of the bottle body 240 is pressed into the holding space 910. At this time, the bottle cap 250 moves in the third through hole 920 in a direction away from the bottom surface of the holding space 910, so that the liquid storage bottle can be in a horizontal state and be loaded into the holding space 910.

[0084] In some embodiments, as Figure 12 As shown, the outer surface of the bottom wall of the liquid storage bottle rack 900 has a guide groove 963, and the inner surface of the bottom wall of the liquid separation box has a guide rail 112. When the liquid storage bottle rack 900 and the liquid separation box are assembled, the guide rail 112 is located in the guide groove 963, and the guide groove 963 extends along the first direction. The guide rail 112 can move along the first direction in the guide groove 963. It can be understood that the movement between the liquid storage bottle rack 900 and the liquid separation box in directions other than the first direction is limited by the action force between the guide rail 112 and the guide groove 963, that is, the guidance of the liquid storage bottle rack 900 is achieved.

[0085] In some embodiments, as Figure 13 As shown, an elastic arm 931 is provided at the sixth end of the liquid storage bottle rack 900, and the projection of the inner surface of the elastic arm 931 at the fifth end of the liquid storage bottle rack 900 is located in the third through hole 920, and the elastic arm 931 can generate elastic deformation in the first direction. It can be understood that when the liquid storage bottle is located in the holding space 910, the elastic arm 931 abuts against one end of the liquid storage bottle and pushes the liquid storage bottle toward the fifth end, so that the other end of the liquid storage bottle is aligned with the fifth end of the liquid storage bottle rack 900. The inner surfaces abut against each other, so that the two ends of the liquid storage bottle are clamped by the elastic arm 931 and the inner surface of the fifth end of the liquid storage bottle rack 900, thereby making the liquid storage bottle securely placed in the holding space 910. Moreover, when the liquid storage bottle is taken out of the holding space 910 or when the liquid storage bottle is placed into the holding space 910, the elastic deformation of the elastic arm 931 can avoid the liquid storage bottle, thereby making it easier for the liquid storage bottle to be placed in the holding space 910 or to be taken out of the holding space 910.

[0086] Optional, such as Figure 13As shown, an operating groove 940 is provided on the side of the liquid storage bottle rack 900 near the sixth end. In order to make more effective use of the holding space 910, it is necessary to make the liquid storage bottle basically occupy the holding space 910, so that the distance between the liquid storage bottle and the inner wall of the holding space 910 is small, resulting in that when the liquid storage bottle needs to be taken out of the holding space 910, it is difficult for the user's hand to reach between the inner wall of the holding space 910 and the liquid storage bottle, and the liquid storage bottle is difficult to be taken out; by providing the operating groove 940, the user's hand can be extended into the holding space 910 through the operating groove 940 and lift the part of the liquid storage bottle near the sixth end, thereby facilitating the removal of the liquid storage bottle from the holding space 910.

[0087] In some embodiments, as Figure 14 As shown, the bottom surface of the liquid storage cavity 210 is concave to form a second groove 243 and a fourth protrusion 242 is formed at a corresponding position on the outer surface of the bottle body 240. The inner surface of the liquid storage bottle holder 900 is concave to form a third groove 901. The third groove 901 extends along the first direction, and in the first direction, the size D1 of the fourth protrusion 242 is smaller than the size D2 of the third groove 901. When the liquid storage bottle is located in the holding space 910, the fourth protrusion 242 is located in the third groove 901. It can be understood that the liquid storage bottle is formed by stamping or injection molding. A second groove 243 is formed and a fourth protrusion 242 is formed at a corresponding position on the outer surface of the liquid storage bottle. The third groove 901 is provided to avoid the fourth protrusion 242. At the same time, by making the size D1 of the fourth protrusion 242 smaller than the size D2 of the third groove 901 in the first direction, the fourth protrusion 242 can slide in the third groove 901 along the first direction during the installation or removal of the liquid storage bottle, thereby reducing the possibility of motion interference between the fourth protrusion 242 and the third groove 901.

[0088] In some embodiments, as Figure 15As shown, the liquid delivery device 10 further includes a venturi tube 800, and the liquid separation box further has a second liquid outlet 160. The venturi tube 800 includes a venturi tube body 820 and a funnel-shaped structure 830. One end of the venturi tube body 820 is a water inlet, and the other end of the venturi tube body 820 is a water outlet. The diameter of the venturi tube body 820 decreases in the direction extending from one end to the other end to form a contraction section, and a throat is formed near the other end of the contraction section. A funnel-shaped structure 830 is connected to the throat of the contraction section. The end of the structure 830 away from the venturi tube body 820 has a maximum opening and forms a negative pressure suction port 810. When water flows from the water inlet to the water outlet, a negative pressure is formed in the contraction section, thereby forming a suction force at the negative pressure suction port 810. The second liquid outlet 160 is connected to the negative pressure suction port 810, so that the venturi tube 800 can extract the detergent in the liquid separation chamber 110 through the second liquid outlet 160 and mix it with water to form a multi-bubble washing mixture. The washing mixture can also be sprayed into the washing drum, thereby improving washing efficiency. The detergent can include different types. By controlling the distance between the liquid inlet 150 and the second liquid outlet 160, the proportion of detergent in the washing mixture can be controlled. The relevant structures of the liquid inlet 150 and the second liquid outlet 160 are exemplarily described below.

[0089] Combine Figure 3 and Figure 15 The number of the first through hole 120, the second through hole 220, the liquid inlet 150, the suction tube 700 and the liquid storage bottle is two. The liquid inlet end and the liquid outlet end of the liquid pump 400 are both two. The liquid inlets of the two liquid pumps 400 pass through the two first through holes 120 respectively and can be connected with the two second through holes 220 respectively. The two suction tubes 700 are respectively located in the two liquid storage bottles and are connected with the two second through holes 220. The two liquid outlet ends of the liquid pump 400 are respectively connected with the two liquid inlets 150. It can be understood that the two first through holes 120, the second through holes 220, the liquid inlet 150 and the suction tube 700 are respectively connected, thereby forming two independent circulation channels.

[0090] A first cavity and a second cavity are formed in the two liquid storage bottles respectively, that is, the liquid storage cavity 210 in the liquid storage bottle forms a first cavity and a second cavity respectively, the first cavity is used to hold the main detergent, and the main function of the main detergent is to clean clothes, and the second cavity is used to hold the auxiliary detergent, and the function of the auxiliary detergent is to assist in cleaning clothes or to achieve other functions. For example, the auxiliary detergent can be a special detergent for cleaning specific types of dirt. For example, the auxiliary detergent can be a softener for making clothes softer. Among them, the two liquid inlets 150 respectively form a first liquid inlet 151 and a second liquid inlet 152. The first liquid inlet 151 is connected to the first cavity, and the second liquid inlet 152 is connected to the second cavity. It can be understood that the first cavity and the first liquid inlet 151, as well as the second cavity and the second liquid inlet 152 are connected through two independent liquid circulation channels, so that the main detergent and the auxiliary detergent in the first cavity and the second cavity will not affect each other during the flow process. At the same time, the distance between the first liquid inlet 151 and the second liquid outlet 160 is smaller than the distance between the second liquid inlet 152 and the second liquid outlet 160, so that the negative pressure suction port 810 can inhale more main detergent, thereby increasing the proportion of main detergent in the washing mixture output by the venturi tube 800, thereby improving the cleaning effect on clothes.

[0091] In some embodiments, as Figure 16 As shown, a second guide cylinder 162 is protruding from the outer surface of the bottom of the liquid separation box. The second guide cylinder 162 does not have a bottom surface but only a side surface. One end of the second guide cylinder 162 is connected to the bottom surface of the liquid separation box. The connection point is the second liquid outlet 160 for guiding the washing mixed liquid out of the liquid separation box. The other end is connected to the negative pressure suction port 810 of the venturi tube 800.

[0092] In some embodiments, as Figure 16 As shown, the outer surface of the bottom surface of the liquid-separating box is convexly provided with a second guide cylinder 162 having a bottom surface and a side surface. In the thickness direction parallel to the bottom surface of the liquid-separating box and in the thickness direction perpendicular to the bottom surface of the liquid-separating box, the second guide cylinder 162 protrudes from the bottom surface of the liquid-separating box. A second liquid outlet channel 161 is formed in the second guide cylinder 162. The second liquid outlet channel 161 is connected to the liquid-separating chamber 110, and the end of the second liquid outlet channel 161 connected to the liquid-separating chamber 110 forms a second liquid outlet 160. It can be understood that the second guide cylinder 162 not only protrudes from the liquid-separating box in the thickness direction of the bottom surface of the liquid-separating box, but also protrudes laterally from the bottom surface of the liquid-separating box in the direction perpendicular to the thickness, so that the second guide cylinder 162 is not completely located directly below the liquid-separating box, but is offset in the laterally direction away from the liquid-separating box, so that the second guide cylinder 162 and the venturi tube 800 can avoid other parts of the liquid delivery device 10 at the bottom of the liquid-separating box, such as pipelines or wiring harnesses.

[0093] The second guide cylinder 162 is offset in the direction away from the liquid-separating box in the horizontal direction, and the second liquid outlet 160 can only be opened in the overlapping area of the projection of the second guide cylinder 162 on the bottom surface of the liquid-separating box and the bottom surface of the liquid-separating box. Therefore, the second liquid outlet 160 is not completely coaxial with the second guide cylinder 162. In the thickness direction perpendicular to the bottom surface of the liquid-separating box, the second liquid outlet 160 is offset to the side closer to the liquid-separating box compared to the second guide cylinder 162. At the same time, because the second guide cylinder 162 is offset in the direction away from the liquid-separating box in the horizontal direction, a portion of the second guide cylinder 162 cannot use the bottom surface of the liquid-separating box as its bottom surface, but instead has its own independent bottom surface. The second liquid outlet 160 can be opened on the side or bottom surface of the second guide cylinder 162. In order to obtain a larger second liquid outlet 160, the second liquid outlet 160 can be opened on the side or bottom surface of the second guide cylinder 162. In this way, the communication area between the second liquid outlet 160 and the liquid separation chamber 110 is increased, so that more detergent can flow out of the liquid separation chamber 110 through the second liquid outlet 160 .

[0094] Moreover, in the thickness direction parallel to the bottom surface of the liquid separating box, the part of the funnel-shaped structure 830 close to the liquid separating box and close to the negative pressure suction port 810 is located on the side of the second guide cylinder 162 away from the liquid separating box, thereby making the connection between the negative pressure suction port 810 and the second liquid outlet 160 more reliable.

[0095] Optional, such as Figure 17 As shown, the outer surface of the bottom surface of the liquid separating box is further protruded by a mounting plate, which extends in a thickness direction perpendicular to the bottom surface of the liquid separating box. In the thickness direction parallel to the bottom surface, a portion of the second guide cylinder 162 protrudes from the outer surface of the bottom surface of the liquid separating box, and another portion protrudes from the outer surface of the mounting plate. The second liquid outlet 160 is located in the liquid separating box and the outer surface of the mounting plate forms at least a portion of the bottom surface of the second guide cylinder 162.

[0096] In some embodiments, combined Figure 17 and Figure 18 The venturi tube 800 is fixedly connected to the liquid separation box. Specifically, on the outer surface of the liquid separation box, the outer circumference of the second guide cylinder 162 is protruded outward by at least one mounting cylinder 163 and at least one positioning column 164. The venturi tube 800 also includes a second connecting structure 821 located on the side of the venturi tube body 820. The second connecting structure 821 is provided with a mounting hole and a positioning hole 823. The positioning column 164 can pass through the positioning hole 823 and make the mounting hole coaxial with the mounting cylinder 163. The mounting hole can be detachably connected to the mounting cylinder 163 through a connecting piece. It can be understood that by arranging a connecting structure on the side wall of the venturi tube body 820, the connecting piece can have a larger operating space.

[0097] In some embodiments, as Figure 19As shown, the liquid separating box includes a liquid separating box body 181 , a liquid separating box cover 182 and a top cover 183 . The liquid separating box body 181 is fixedly connected to the liquid separating box cover 182 , and the liquid separating box body 181 and the liquid separating box cover 182 surround and form a liquid separating cavity 110 . The side of the liquid separation box cover 182 facing away from the liquid separation chamber 110 has a fourth convex wall 1821, the top cover 183 is fixedly connected to the fourth convex wall 1821, and the fourth convex wall 1821 and the top cover 183 are surrounded to form a condensation chamber 184; and / or, the side of the top cover 183 facing the liquid separation chamber 110 is composed of the fourth convex wall 1821, the liquid separation box cover 182 is fixedly connected to the fourth convex wall 1821, and the fourth convex wall 1821 and the liquid separation box cover 182 are surrounded to form a condensation chamber 184; wherein, the liquid separation box cover 182 is also surrounded by the top cover 183 to form an air pressure balance channel 186, and the air pressure balance channel 186 is connected to the washing drum through the air pressure balance pipe 187, and the air pressure balance channel 186 is connected to the condensation chamber 184, for condensing the moisture in the hot and humid air entering the condensation chamber 184 through the air pressure balance pipe 187. It should be noted that when water is poured into the washing drum, if the washing drum The formation of a closed cavity in the washing drum will cause the air pressure in the washing drum to continue to increase, which will eventually make it difficult or even impossible to continue filling water. The washing drum needs to be connected to the space where the liquid delivery device 10 is located through the air pressure balance pipe 187, so that the humid air in the washing drum will enter the space where the liquid delivery device 10 is located. When the washing drum is drying, the hot and humid air passes through the air pressure balance pipe 187 to connect the washing drum with the space where the liquid delivery device 10 is located. In this state, the amount of water vapor in the air is greater. If the humid air directly enters the space where the liquid delivery device 10 is located, the water vapor in the humid air will form droplets in the entire space after condensation. If the droplets adhere to the outer surface of the liquid storage part 200, when the user pulls out the liquid storage part 200, these droplets will drip onto the ground or the user's body, resulting in a reduced user experience.

[0098] By forming a condensation chamber 184 between the liquid separation box cover 182 and the top cover 183, and connecting the air pressure balance pipe 187 to the condensation chamber 184 through the air pressure balance channel 186, the first direction (the first direction is as shown in FIG. Figure 13As shown by the arrow in the middle, the air pressure balance channel 186 is located on the side of the liquid separation box away from the liquid storage member 200, and the first condensation chamber 184 is located on the side of the liquid separation box cover 182 close to the air pressure balance channel 186. It can be understood that the fourth convex wall 1821 is located on the side of the liquid separation box cover 182 close to the air pressure balance channel 186, and / or the top cover 183 is located on the side of the liquid separation box close to the air pressure balance channel 186, that is, the condensation chamber 184 is located on the side away from the liquid storage member 200. At the same time, the liquid separation box cover 182 is provided with a second communication port 185 inside the condensation chamber 184. The second communication port 185 The condensation chamber 184 and the liquid separation chamber 110 are connected, so that the water vapor in the humid air condenses in the condensation chamber 184 to form droplets, and then falls into the liquid separation chamber 110 through the second connecting port 185. The condensation chamber 184 is located on the side away from the liquid storage part 200, so that the second connecting port 185 is away from the liquid storage part 200, so that the condensed droplets fall into the liquid separation chamber 110 from a position away from the liquid storage part 200, thereby reducing the possibility of droplets adhering to the surface of the liquid storage part 200, and reducing the possibility of droplets falling on the ground or on the user's body when the user pulls out the liquid storage part 200, thereby improving the user experience.

[0099] In some embodiments, as Figure 20 As shown, the fourth convex wall 1821 includes an outer convex wall 1822 and an inner convex wall 1823. The outer convex wall 1822 and the top cover 183 surround a condensation chamber 184, and / or the outer convex wall 1822 and the liquid separation box cover 182 surround a condensation chamber 184; the inner convex wall 1823 extends along a curve in the condensation chamber 184 to form a condensation channel 1842 in the condensation chamber 184. By extending the inner convex wall 1823 along the curve to form the condensation channel 1842 extending along the curve, the condensation channel 184 is increased. 2, so that the condensation channel 1842 can be in more complete contact with the moist air entering the condensation chamber 184, thereby accelerating the condensation speed of the moist air; at the same time, the side walls of the outer convex wall 1822 and / or the inner convex wall 1823 adjacent to the condensation channel 1842 are protruded with heat exchange fins 1845, and the multiple heat exchange fins 1845 are arranged at intervals along the extension direction of the condensation channel 1842, thereby further increasing the surface area of the outer surface of the condensation channel 1842 and further accelerating the condensation speed of the moist air.

[0100] In some embodiments, as Figure 20 As shown, there are multiple condensation channels 1842, and the projections of the multiple condensation channels 1842 on the first plane are at different distances from the projections of the air pressure balance channel 186 on the first plane. The condensation channel 1842 with the smallest distance is the first condensation channel 1846, that is, the first condensation channel 1846 is the one closest to the air pressure balance channel 186 among the condensation channels 1842, wherein the first plane is a plane with the thickness direction of the liquid separation box cover 182 as its normal.

[0101] At the same time, the liquid separation box cover 182 also has a water inlet pipe 188, which is connected to the first condensation channel 1846. The number of the second communication openings 185 on the portion of the liquid separation box cover 182 located in the first condensation channel 1846 is greater than the number of the second communication openings 185 on the portion of the liquid separation box cover 182 located in the second condensation channel 1847. The second condensation channel 1847 is a condensation channel other than the first condensation channel 1846. It can be understood that the water inlet pipe 188 can introduce water into the first condensation channel. The detergent flows into the channel 1846 and into the liquid separation chamber 110 through the second connecting port 185 located in the first condensation channel 1846, so that the detergent in the liquid separation chamber 110 is mixed with the water. That is, the first condensation channel 1846 is not only used to realize the condensation function, but also used to realize the water inlet function. By setting more second connecting ports 185 in the first condensation channel 1846, the water flowing in from the water inlet pipe 188 can flow into the liquid separation chamber 110 from multiple different positions, so that the detergent can be more fully mixed with the water.

[0102] Optional, such as Figure 20 As shown, heat exchange fins 1845 are disposed within second condensation channel 1847 and spaced along the extension of second condensation channel 1847. This further improves the condensation capacity of second condensation channel 1847 while eliminating heat exchange fins 1845 within first condensation channel 1846. This reduces the blocking effect of heat exchange fins 1845 on the flow of water from water inlet pipe 188 into first condensation channel 1846, thereby lowering the flow resistance of liquid in first condensation channel 1846. Optionally, the projection of second condensation channel 1847 on the bottom surface of liquid separation chamber 110 is located within first liquid outlet 111. This allows droplets condensed within second condensation channel 1847 to drip directly out of liquid separation chamber 110 through first liquid outlet 111 after entering liquid separation chamber 110, further reducing the possibility of condensed water that drips into liquid separation chamber 110 splashing onto the outer surface of liquid storage member 200.

[0103] Optional, such as Figure 20 As shown, the liquid separation box cover 182 also has a third liquid outlet 189, which is connected to the first condensation channel 1846, and the third liquid outlet 189 can guide water to the sealing leather bowl of the washing machine door. The water entering the first condensation channel 1846 from the water inlet pipe 188 can flow out from the third liquid outlet 189 and rinse the foam attached to the sealing bowl of the washing machine door.

[0104] In some embodiments, as Figure 21 As shown, the outer surface of the side and / or bottom of the liquid separation box has a pipeline fixing part 193, and the pipelines of the liquid delivery device 10 and the washing machine can be fixed to the outer surface of the liquid separation box through the pipeline fixing part 193.

[0105] In some embodiments, as Figure 1 As shown, a temperature sensor (e.g., a positive temperature coefficient thermistor) is provided on the outer surface of the liquid extraction tube 500. The temperature sensor can obtain the temperature of the area where the temperature sensor is located in the liquid extraction tube 500, thereby determining whether the fluid flowing in the liquid extraction tube 500 is liquid or air. It is understandable that when liquid contacts the area where the temperature sensor is located, the heat absorption capacity of the area where the temperature sensor is located is greater than the heat absorption capacity of air when the area where the temperature sensor is located is in contact with the temperature sensor. Therefore, if the temperature of the area where the temperature sensor is located is greater than the temperature threshold, it indicates that the fluid flowing in the liquid extraction tube 500 is liquid. If the fluid flowing in the liquid extraction tube 500 is liquid, it indicates that the remaining amount of detergent in the liquid storage chamber 210 is sufficient. If the fluid flowing in the liquid extraction tube 500 is liquid, it indicates that the remaining amount of detergent in the liquid storage chamber 210 is insufficient.

[0106] In some embodiments, as Figure 1 As shown, a transmittance sensor 902 is provided on the outer surface of the liquid extraction tube 500, and the size of the bubbles in the liquid extraction tube 500 can be obtained through the transmittance sensor 902. It can be understood that when the amount of detergent in the liquid storage chamber 210 is insufficient, the suction tube 700 will inhale a portion of air while inhaling the detergent, and the less the amount of detergent, the more air will be inhaled, so that the bubbles in the liquid extraction tube 500 are larger or the number of bubbles is greater. When the size of the bubbles in the liquid extraction tube 500 obtained by the transmittance sensor 902 is greater than a preset volume threshold, or the speed at which the bubbles are generated is greater than a preset speed threshold, the control alarm component outputs a liquid shortage prompt signal to prompt the user to replenish detergent.

[0107] In some embodiments, as Figure 22 As shown, the washing device 1 includes a housing 20, a washing tub 30 and a Figures 1 to 21 In the liquid dispensing device shown in any one of the items, the shell 20 has a accommodating chamber 21, the washing drum 30 is located in the accommodating chamber 21, the liquid dispensing device 10 is located in the accommodating chamber 21, and the first liquid outlet 111 is connected to the washing drum 30, so that the liquid dispensing device 10 can input detergent into the washing drum 30.

[0108] The shell 20 includes a front panel 22 and a liquid separation box frame 23. The front panel 22 is provided with a liquid storage port 221. The liquid storage part 200 can be drawn out from the liquid separation box through the liquid storage port 221, so that it is easy to operate when detergent needs to be added to the liquid storage part 200.

[0109] like Figure 23As shown, the front panel 22 is provided with a side wall concave toward the accommodating cavity 21 around the liquid storage opening 221, and a hook 24 and a connecting protrusion 25 protruding to the liquid storage opening 221 are provided on the side wall. The connecting protrusion 25 is provided with a second mounting hole 26. At the same time, the lower part of the liquid separation box frame 23 is provided with a first mounting hole 27. The front surface of the liquid separation box is provided with a third mounting hole 180. The hook 24 is used to limit the liquid separation box frame 23. By making the liquid separation box frame 23 abut against the liquid separation box frame 23, the liquid separation box frame 23 can be achieved. Preliminary positioning, at the same time, the central axis of the first mounting hole 27, the central axis of the second mounting hole 26 and the central axis of the third mounting hole 180 are collinear, and the connecting parts are sequentially passed through the first mounting hole 27, the second mounting hole 26 and the third mounting hole 180 to fix the liquid separating box frame 23, the front panel 22 and the liquid separating box in connection, that is, the liquid separating box frame 23, the front panel 22 and the liquid separating box are fixedly connected at the same time by connection, thereby reducing the steps required for assembling the liquid separating box frame 23, the front panel 22 and the liquid separating box.

[0110] In some embodiments, combined Figure 24 and Figure 25 The liquid storage part 200 includes a liquid storage part 200 body and a hand buckle 960. The hand buckle 960 is fixed to the liquid storage part 200 body. The lower part of the hand buckle 960 protrudes from the liquid storage part 200 body, and the hand buckle 960 and the liquid separation box are located on both sides of the liquid separation box frame 23. At the same time, the lower part of the hand buckle 960 is facing away from the liquid separation box frame 23. The surface has a hand buckle 961 to facilitate the user to pull out the liquid storage part 200; the lower part of the hand buckle 960 is facing the liquid separation box frame 23. The surface has a buckle 962, and the liquid separation box frame 23 has a card slot 28, and the card slot 28 is separated from the first mounting hole 27 on the left and right sides. The front surface of the liquid separation box is provided with an avoidance hole 190 corresponding to the slot 28, thereby reducing the possibility of interference between the buckle 962 and the liquid separation box. At the same time, the depth direction of the slot 28 is parallel to the first direction. When the liquid storage part 200 is pushed into the liquid separation box, the buckle 962 can be engaged with the slot 28, thereby reducing the possibility of the liquid storage part 200 accidentally escaping from the liquid separation box under the action of external force disturbance. The external force disturbance may be caused by the vibration of the washing machine. When the liquid storage part 200 is pulled out of the liquid separation box, the buckle 962 disengages from the slot 28.

[0111] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
